Does any one have a different book reader than Mobibook.

I finally came to realize that mobibook is a cross over from the windows pda world. While the result works well enough. I has some quirks. It's not always on, like other palm apps. Everytime you switch back from another application it seems to have to reload. The wait is agonizing when you are used to better. Also there seems to be something wrong when bringing the pda out of sleep. If the last active app was the reader, and you click the schedule button, It comes back up with the reader instead of going directly to your schedule.
